Dr John A. Tadross

Research focus

My research focuses on elucidating the human neurocircuitry regulating body weight.

Background and experience

I have combined clinical medicine with bench research throughout my professional training. This included an MB/PhD Programme at Imperial College (2003-2014), an Academic Foundation Programme in Cambridge (2014-2016), an Academic Clinical Fellowship (Cambridge 2016-2019) and an NIHR Clinical Lectureship (Cambridge, 2019-2022). I am a currently a Consultant in Histopathology and Solid Tumour Molecular Pathology at Cambridge University Hospitals (CUH) and Molecular Pathology Clinical Lead for the East Genomics Laboratory Hub. I am also an Affiliate Investigator in the Wellcome–MRC Institute of Metabolic Science where my research focuses on gleaning the most data possible from precious human tissue samples.

Working at the IMS-MRL

My research focuses on elucidating the human neurocircuitry regulating body weight by applying multi-modal single-cell ‘omics’ techniques to human tissue samples, and I lead the “normal hypothalamic atlas project” in collaboration with Cambridge Brain Bank and Giles Yeo. I also collaborate with Professor M Gurnell & Dr R Casey, providing endocrine pathology input to their ongoing programs. The best thing about working at the IMS-MRL is the awesome working environment and appetite for high-risk, high-reward science.
